Title: Data flow control with duplicate acknowledgment
Inventor: LUDWIG REINER
IPC: H04L1/18
Filed: 2004-12-22
Granted: 2014-06-03
Abstract: A method of controlling the flow of an amount of data from a sending peer to a receiving peer of a predetermined communication protocol is described. The method comprise dividing the amount of data into a plurality of data segments, where the data segments are ordered in a sequence. The segments are sent to the receiving peer in the order of said sequence. The receiving peer acknowledges the correct receipt of a data segment and identifies the last correctly received data segment of the sequence that was received in the proper order of the sequence. The sending peer is arranged such that if it receives a threshold number of duplicate acknowledgements, it performs a retransmission. The threshold number that trigger a retransmission is an adaptive parameter determined based on the size of a receive window, the size of the receive window representing a number of data segments which can be stored in a buffer space at the receiving peer.
